Actress Jessica Biel gave quite an eyeful to shutterbugs in Puerto Rico last weekend.

The 30-year-old actress went solo to a beach and kept tongues wagging at the flawless physique she is known for.

Biel, who once landed Esquire magazine's 'Sexiest Woman Alive" title, frolicked in the Atlantic Ocean covered up in an O'Neill wetsuit top but bared her famous derriere in a bikini bottom to remind us she has one of the best bodies on the planet. (See the Pictures Here)

Biel was in Puerto Rico enjoying her downtime solo while her fiancé pop singer-turned-actor Justin Timberlake was away shooting his latest movie "Runner, Runner", and before she hits the publicity pavement hard core to promote her next film, the remake of "Total Recall," which will hit theaters this summer.

Timberlake's film "Runner, Runner" will hit theaters in 2013. It is about a businessman who gets caught up in the world of offshore online gaming and stars Ben Affleck.

The future Mrs. Justin Timberlake had previously been under the radar since their engagement.

Biel and Timberlake have been dating on and off since 2007. Timberlake proposed to Biel with an estimated $130,000 diamond ring and the stars are in the midst of planning their summer nuptials.
